The six-day warm stretch that Billings' residents enjoyed last week was among the warmest in the past 50 years.
The past six days, which included highs in the low 70s, was the second highest for average temperatures, according to the National Weather Service. During the six days, the average temperature was 55.6 degrees. The highest average for the same six days was 56.3 degrees set in 1983.
"During that stretch, temperatures were well above normal, obviously. The departure from normal was 13 to 19 degrees depending on the day," said Tom Frieders, meteorologist with the National Weather Service office in Billings.
Friday's high of 64 degrees tied the previous record, and Saturday morning's low temperature of 52 degrees broke the record 47 degrees set in 2005.
Saturday's high of 69 degrees approached the record of 72 degrees and Sunday's high of 65 came close to the record high of 69.
The National Weather Service has maintained records in Montana since 1934.
